The interior diamond coating reflects up to 95% of usable PAR back onto your canopy. The result: a more uniform PPFD all the way into the corners, fewer light losses and noticeably better yields for the same LED grow light wattage.
The 22 mm steel tubes comfortably carry the combined weight of an LED grow light, a carbon filter and the extraction kit. Solid metal connectors and tool-free assembly keep the tent perfectly stable through every flowering cycle.
Multiple ducting ports (upper and lower) for intake/exhaust, an inspection window so you can monitor without opening the tent, and reinforced zipped doors. You keep full control over temperature, humidity and odour management inside your indoor grow space.
The removable tray catches watering splashes and any potential leaks. It pops out in seconds and is easy to wipe down between cycles — spotless hygiene and zero risk to the flooring underneath your grow tent.
Every G-PRO Diamond tent is checked in our workshop before shipping. BloomLED, a French growshop expert for more than 10 years, backs the tent with a 2-year warranty and supports you by phone or email for setup and grow-room configuration.
For a 1.44 m² footprint, plan on 400 W to 600 W of quality LED grow light (efficacy ≥ 2.5 µmol/J). That range is ideal to cover both vegetative growth and flowering with a uniform PPFD, without overheating the tent.
Is Mylar Diamond 600D really better than standard mylar?Yes. Compared to standard 210D mylar, the Diamond 600D coating provides higher reflectivity (~95% vs ~85%) and roughly double the durability. Across a flowering cycle that translates into a more consistent peripheral PPFD and improved final yields.
Which carbon filter pairs well with this tent?For a 120x120x200, a 150 mm carbon filter paired with a 250-360 m³/h inline fan is a great match. The upper duct port accepts the diameter without an adapter, and the internal straps allow a clean ceiling-suspended setup with no stress on the frame.
Is the assembly beginner-friendly?Absolutely. The G-PRO Diamond frame goes together without tools thanks to its snap-fit connectors, in 20 to 30 minutes. The illustrated manual and BloomLED's email/phone support are there if you need a hand.
The premium standard for a 120x120 grow tent: Mylar Diamond 600D, 22 mm tubes and a 2-year BloomLED warranty — the perfect ecosystem to unlock the full potential of your LED grow light.
